If prime95 failed it basicly means your cpu isn't 100% stable, but seeing it only happend after 10 hours don't really think it minds that much
Temps can have a drastic and direct effect on stability of a CPU. The higher the temp, the more random motion there is in the material--more random motion means more chaos, means more likelihood of a diode/transistor, etc. not functioning properly. So yeah, it's a big deal. And indirectly, higher overall ambients can affect how clean the power is coming from the PSU (for the same reasons).
